Description

TECHNICAL FIELD

[0001] The present invention relates to an anti-fouling printing sheet having a self-cleaning property based on a hydrophilic action.BACKGROUND ART

[0002] Photocatalyst activation material, which is a hydrophilic material and exhibits a surface-cleaning effect based on super-hydrophilicity, is envisaged to exhibit a so-called anti-fouling effect; i.e., to keep surfaces of signboards or the like clean without performing a maintenance procedure.

[0003] In relation to printed products which are directly exposed to the atmosphere or exhibited for a long period, there has been proposed a weather-resistant printed product having a laminate structure which has at least a printing layer, and a protective layer including a photoactivity intercepting layer made of an inorganic substance for intercepting photoactivity and an anti-fouling layer exhibiting photoactivity, the printing layer and the protective layer being sequentially stacked (see Patent Document 1).

[0004] Even when stain...
